GAS` BURNER FOR STOVES.

Application fiied August 8, 1925.A serial Na. 47,797.

This invention relates to a gas burner structure such as used with as or o-ther stoves burning a mixture of gas of hydrocarbon fuel and air. It has hei'etofore been proposed to construct such a. burner comprising a hollow. body having substantially Vertical sides, apertures for the vpassage of the as or combustible mixture being formed in t e top and sides of said body, whichapertures have sometimes been in the form of slots extending across the top -of the body and some distance down along the sides thereof. It lhas also been the practice to construct burners having a plurality of sections each comprising a body, as above described, which Sections have been arranged lin parallel relation. It has been found in practice that when the flame onlthe burner is adjusted to be low or small that the flame does not extend to the openings at the sldes of the burner body. There is always a tendency for the gas or combustible mixture' to rise from the burner and this tendency is augmented by the draft' through and around the burner caused by the heatedtalr above the burner. j and draft at the burner has caused the flame to be limited to the top surface of the burner, so that there are openings in the burner at which there is no flame and at which the gas or combustible mixture may escape unburned.

It is an object of this invention, therefore,'

to construct a vgas burner having openings therein for the passage of the gas or combustible mixture so arranged that'when the' flame is turned low theflame will extend to all' of said openings and throughout their entire extent. A

It is a further object of the 'invention to provide a burner having a. surface through which the openings are formed for the passage of the gas of combustible mixture;

all of which surface faces upwardly.

It is still another object of the invention to provide la gas burner having a surface at its top substantially horizontal and having surfaces of its sides inclined downwardly, 'the passages for the gas or combustible mixture extending through all ofjisaid surfaces.

It is still another object of the invention to provide a gas burner having one or more Sections with slots extending tran'sversely This upward movement i thereof for the passa-ge of gas Or combustible mixture, said Sections being beveled or inclined downwardly at their sides substantially to the bottom of said slots.

It is also an. object of the inventionl to provide a burner comprising a plurality' of spaced sections having slots or openings at their tops and sides for the passage of gas or combustible mixture with means for directing the air passing upwardly between said Sections away from said section.

These and other objects and advantages of the invention Will be fully set forth in the following description made in connection with the accompanying drawings in which llike reference characters refer to the same portion 4 by which it is adapted to be connected to the fuel supply, said section 4 opening into a hollow transverse portion 5, which portion 5, in turn, opens into and is connected to a plurality of transverse sec- Ations 6 extending across said body portion 5 and substantially at right angles thereto at each side thereof. The portion 5`thus forms, in effect, a common portion for the Htransverse Sections 6. Itwill be noted that the sections 6 are separated by the spaces 7 fornied therebetween at each side of the portion 5. The burner is provided' at its top with a multiplicity of openings 8 for the passage of gas or combustible mixture thereof. While these openings may take various shapes, in the embodiment of the invention illustrated, they are shown 'as narrow slitsv or slots extending transversely of section 6 in substantial parallel relation. It `will be noted 'that the top' portion of the burner having the slots 8, therefore, extends above the 'top surface of the portion 5 between the 'Sections and that said projecting portion has ,the hoi'izontal top surfaces 6a and the downwardly inclined or beveled surfaces 6b at it will be ignited. The flame will extend 'along thesurface 6a and 6b andl it will be i rcadily seen that the air ascending through the spaces ,7 will not come in direct con-` tact with the flame of gas issuing through the openings 8 since the surfaces 6a and 6b both face upwardly. The gas issuing through the slots 8 in the surface Gbis there- 'applicant fore not carried upwardlybythe rising air and the same remains ignited throughout the entire length of the openings 8 no matw ter how small the flame is adjusted. Furthermore, the air rising through the spaces 7 is directed away from the surface 6b by the inclined surface 6c so that the tendency of this air to carry the gas or combustible mixture upward in unburned condition is still further lessened. W'hen `the burner is Operating, there'fore, the flame', as stated, extends throughout the .entire length of the openings 8 and across the entire portion ofsurfaces 6a and 6b so that there is no opening without flame and through which the 'gas or combustible mixture may escape unburned. The burner therefore is very efficient for the combustion of the gas or comvbustible mixture and no unburned gas or combustible mixture can escape to cause an odor.

From the above description it is seen that applicants have provided a very simple and eflicient form of gas burner and one which overcomes aserious objection to burners heretofore used. The burner is very simple in construction and easily and inexpensively made. The same has been amply demonstrated in actual practice and found to be very successful and eflicient and is now being commercially manufactured.

It will, of course, be understood, that various changes may be made in the form, details, arrangement and proportions of the parts without depart-ing from the scope of invention, which, generally stated, consists in a device capable of carr ing out the objects above set forth, in t e novel parts and combinations of parts disclosedand defined in the appnded claims.

W'hat is claimed is: 1. A gas burner comprising a pluralityof vspaced elongated adjacent hollow sections,

said sections each having a series'of spaccd slots extending thereacross, the tops of said Sections comprising horizontal flat top portions and side portions inclined downwardly therefrom, the lower vedge of said inclined portions terminating substantially at the bottom of said slots, said -sections having means below'said inclined portions for directing the air away from said inclined portions and slots.

2. A gas burner comprising a longitudinally extending hollow section having a top surface and having portions with surfaces sloping downwardly at each side thereof, a plurality of slots extending transversely of the top of said' section to the edges thereof and communicating with 'its interior, said section having means at each side below said downwardly sloping portions for directing air away from said portions and slots.

8. A gas burner comprising a longitudinally extending section having a'flat horizontal top surface and surfaces at each side thereof extending downwardly and outwardlyl from said surface, a plurality of transv'erse slots extending across said burner having their bottoms at the lower edges of said downwardly inclined surfaces, said section having downwardly and inwardly -inclined surfaces extending from the lower edges of the downwardly inclined surfaces, said section being hollow whereby gas may pass therethrough and out of said slots.

n4...A gas burner comprising a longitudinally extending section having a flat horizontal top surface and surfaces at each side thereof extending downwardly and outwa'rdvly from said surface, a plurality of transverse slots extending across said burner havlng their bottoms at the lower edges of said downwardly inclined surfaces, said section having downwardly and inwardly inclined' i surfaces extendingfrom the lower edges of the downwardly inclined surfaces, said section being hollow ,whereby gas may pass therethrough and out ofV said slots, said burner having al common Chamber with which all of said Sections communicate.

In testimony whereof'we atfix our signatures.
